A comparison of psoriasis-like eruptions in Kawasaki disease (KD) with classic psoriasis shows a distinct phenotype with greater remission, report Ellen S. Haddock, AB, MBA and coauthors from the School of Medicine at the University of California, San Diego.

Investigators performed a retrospective study of 11 KD cases with a psoriasiform eruption matched by gender, age, and ethnicity with psoriasis-only and KD-only controls. Genotyping was performed in 10 cases for a deletion of two late cornified envelope genes associated with pediatric-onset psoriasis.

KD-associated eruptions were similar to classic psoriasis in presentation, but with less frequent diaper area involvement, more crust, more serious exudate, and significantly higher remission (91% vs. 23%; P less than .001), the authors noted.

The findings indicate that despite similarities to classic psoriasis, “this appears to be a distinct phenotype with significantly greater propensity for remission,” the authors concluded.
